Nitric Acid 67% Laboratory / Technical Grade *Excellent for gold refining Nitric Acid 67% (42° Baumé) (HNO3) is a highly corrosive mineral acid widely used in various industrial application.  It is a clear to pale yellow in color and is a strong oxidizing agent known for its corrosive properties.  It is commonly used in chemical manufacturing, metal processing, and as a laboratory reagent.   Nitric Acid 67% Lab/Tech Grade Safety Data Sheet (SDS)  Nitric Acid 67% Lab/Tech Grade Certificate of Analysis (COA) Nitric Acid plays a key role in refining gold, particularly in methods like aqua regia refining and in parting processes.   Urban mining and pcb board gold recovery commonly uses nitric acid to dissolve gold.  *Ships in Level 4 Fluorinated Polyethylene Bottles.  Aqua Regia Gold Refining Process (Most Common Use)Aqua regia is a mixture of nitric acid (HNO₃) and hydrochloric acid (HCl) in a 1:3 ratio. This combination dissolves gold, which neither acid can do alone. Step-by-step Overview:Preparation of Aqua Regia: Mix 1 part nitric acid with 3 parts hydrochloric acid. Dissolution: Add impure gold to the aqua regia. Nitric acid oxidizes the gold to gold ions (Au³⁺). Hydrochloric acid provides chloride ions (Cl⁻) to form chloroauric acid (HAuCl₄), which is soluble. Filtration: Filter the solution to remove impurities and undissolved metals. Precipitation: Add a reducing agent like sodium metabisulfite (Na₂S₂O₅) to the solution. This causes pure gold to precipitate out of solution as fine particles. Washing & Melting: Wash the gold powder, dry it, and melt it to form pure gold bars or granules.

 Refurbished BVV Value Pump 3cfm 220V ONLY ***NOTE: Refurbished products are 100% re-tested at our warehouse to be fully functional. The customer acknowledges that by buying a refurbished product the item may have imperfections or slight damage to the product such as: Major/Minor Scratches Major/Minor Dents Smells or Odors (Cleaned as much as possible at warehouse) This is the BVV™ Brand VE115 3CFM Single Stage Vacuum Pump. Single-stage vacuums pump exhaust into a chamber in the pump, which separates the oil from the pumped gas. Then, the oil is returned and the gas is exhausted.  Please refer to these charts for vacuum specifications at altitude and conversions:   Vacuum at Altitude Chart   Vacuum Conversion Chart     Key Features: Internal Check Valve Oil Mist Filter Cap Larger Oil Reservoir for longer Oil life Lightweight Rubber Feet for noise dampening Reliable, Economical and Efficient.   Specification Free Air Displacement - (CFM) 3CFM # Of Stages 1 Voltage 220v Ultimate Vacuum 5 Pa HP 1/4 Oil Capacity 280ml Weight 15LB Intake Connection 1/4" SAE & JIC     Pump Warranty Information Customers using solvents such as stabilization resins (MinWax™, Gator Venom™ etc.), alcohol and other polar solvents must use the vacuum pumps in conjunction with a cold trap for evacuations in excess of 5 minutes. (Excludes Cactus Juice™)  If the consumer is using the pump for prolonged periods of time exceeding 5 minutes we require that a cold trap is used or the pump warranty is void. These stabilization resins have the ability to break down the internal components of the pump that are plastic resulting in a seized motor voiding all warranties. When evacuation exceeds 5 minutes these solvents begin to vaporize and then re-condense in the vacuum pump reservoir. Once enough solvent re-condenses in the pump displacing the oil the plastic internal components may begin to warp, melt or seize. The use of a cold trap will condense the vapors prior to making their way to the vacuum pump preventing pump damage due to excessive use. Furthermore, Minwax Wood Hardener™ is not to be used with any vacuum pumps, EVER. (A seized motor will result within the first use.) To prevent these issues from happening to your process, change the Oil after each vacuum pump use, Even if the use time is only 5min.
